Dissonance is the opposite of consonance; it describes a combination of notes that sound harsh, unstable, or clashing when played together. It creates tension and a sense of unease in music. Think of dissonance as the musical equivalent of a spicy salsa – it adds flavor and excitement but can be a bit intense. Dissonant intervals and chords are often used to create drama or to lead the listener towards a resolution in the form of consonance. It adds complexity and emotional depth to music.
